SPECIFICATION forming part of Letters Patent No. 708,347, dated September 2, 1902.

Application filed .Tune 30. 1902. Serial No. 113,730. (No model.)

To @ZZ whom it may concern:

Be it known that I, MARTIN HAAs, of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Railroad-Beds, of which the following is a specification.

My invention relates to railroad-beds generally, and more specifically to a peculiar bed of novel construction yadapted to form direct support for the rails without the'use of crossties and peculiar means, in connection with the bed, whereby the rails may be secured.

The invention consists, broadly, in a cement bed upon which the rails rest, the bed having embedded within it longitudinal and transverse twisted or corrugated wiresor strips.

The invention consists, further, in peculiar means also embedded in the cement and iixedly secured therein by the said embedded wires or strips, all as will be fully described in the following specification, with the novel features pointed out in the claims.

For a full understanding of the invention, reference is had to the accompanying drawings, whichform a part of this specification, and in which-- Figure l is a transverse vertical sectional view through the road-bed, showing the embedded wires or strips and the rail-fastening means; and Fig. 2 is a view showing in elevation one of the sockets employed in the railfastening means.

In carrying out my invention I form a cement bed A of suitable width and `thickness and embed in it an upper and a lower series of twisted or corrugated wires B Bf. At proper positions in the cement bed-I 'arrange sockets C, having on opposite sides thereof vertically-disposed ribs D, each of which latter is provided with an upper and lower perforation E, adapted to receive transverse embedded wires, as shown in Fig. 1. The said sockets C are formedwith upwardly-converging side walls and with a vertical screwthreaded perforation adapted to receive the threaded rail-securing bolts F.

A railroad-bed constructed as invented by me renders the use of cross-ties unnecessary, since its construction will provide all necessary or adequate support for the rails. The

longitudinal and transverse series of twisted wires or strips not only provide effective bracing or support, obviating liabilityl of the cement cracking, but in addition also serve to bind and secure the sockets against being loosened by tightly screwing down the railsecuring bolts. The said sockets are further madesecure by reason of their converging sides, which constructionobviously resists upward strain tending to loosen them in the cement.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- l. The combination in a cement railroadbed, of an upper and lower embedded series of wires or strips and internally-screw-threaded sockets having rigid connection with .said wires or strips, substantially as described.

2. The combination in a cement railroadbed of embedded wires,embedded sockets each having means adapted for engagement with said embedded wires, and a screw-threaded perforation adapted to receive a headed and threaded bolt, the latter having suitable means for engaging and securing the rails, substantially asfdescribed.

3. The combination with a cement roadbed, of an upper and lower series of wires or strips, one series arranged transversely and the other serieslongitudinally within the said bed, substantially as described.

4. The combination with a cement railroadbed of` an upper and lower twisted or corrugated series of wires or strips, one series arranged transversely and the other longitudinally within thesaid bed, substantially as described.

5. The combination with a cement roadbed, of embedded transverse and longitudinal wires or strips as specified, internally-screwthreaded sockets having perforated side ribs with the perforations adapted to receive wires embedded in the bed and threaded bolts adapted to enter the said sockets and engage and secure the track-rails, substantially as described.
